There is no absolute good or bad air compressor oil and oil-free, their use of occasions and suitable for different conditions, if it is used for blowing, machining, manufacturing, for power use, choose the oil, micro-oil air compressor can be, but some occasions must use oil-free air compressor, such as food, medicine, precision instruments and other industries. Oil-free air compressors are cleaner and more environmentally friendly than oiled air compressors, but the price of oil-free air compressors is more expensive than oiled ones, and the maintenance cost is also higher.

　　In addition to price, oil-free air compressors and oiled air compressors have the following differences:

　　1, the oil content is different, generally oiled machine oil content is larger, oil-free machine oil content is 0.01ppm, so use this oil content to distinguish between oil and oil-free air compressor. There is also a completely oil-free air compressor, is the use of resin material lubrication, so the final discharge of the gas does not contain oil, known as completely oil-free air compressor.

　　2, the structure is different, whether it is oil-free piston machine or oil-free screw machine they will produce a lot of high temperature in the process of operation, oil compressor oil will take away the high temperature generated in the compression process of the air compressor, so as to cool down the machinery. The oil-free air compressor internal use of a special high-temperature resistant material called Teflon or molybdenum disulfide, instead of oil to solve the high temperature of the air compressor compression process, so as to achieve the purpose of oil-free compression.
